Ask a question


Flush refers to the sudden appearance of a transient red color mainly on the face, neck, or chest. It is due to the dilation of blood vessels and can sometimes be accompanied by hot flashes or difficulty breathing. Most of the time, flushing is benign and linked to an emotion. However, it can also be caused by the absorption of substances such as alcohol or certain medications, or rarely be a symptom of conditions such as a tumor of the pancreas or intestine. In postmenopausal women or those just at the beginning of menopause, hot flashes with flushes are possible.
